Date Oct. 27, 1994A method and installation for reducing emissions during the incinerating of waste results from a combustion chamber, a return situated downstream of the combustion chamber for returning a portion of a flue gas to the combustion chamber in a continuous cycle and a flue gas purification installation; and from situating the flue gas purification installation between the combustion chamber and the return, removing chlorine, heavy metal and sulfur dioxide from the flue gas produced in the flue gas purification installation, and admixing the oxygen required for combustion as pure oxygen with the flue gas to generate synthetic air in the ratio of 4:1 to 1:1, and preferably 2:1 to 1.5:1 while excluding ambient air.
